Thinking about situations like days out or camping and using something like a 12v electric cool box can someone answer the following about the Model 3. Does it have Standard 12v accessory sockets ( i.e. the old cigarette lighter type) If so how many does it have and where are they in the car? Assuming the answer is yes do they stay powered on when the car is not in use? Assuming yes to that does using them when the car is not in use cause any issues such as stopping the car from sleeping?
